HPE Aruba Certified Switching Professional (ACSP) — Question 47

An interface on an ArubaOS switch did not receive any BDPUs and has the spanning tree auto-edge setting. What describes the effect of this setting?

Answer options

• A. The interface has spanning tree disabled on it and ignore BPDUs.
• B. The interface remains forwarding during topology changes.
• C. The interface root path cost is automatically set to 0.
• D. The interface is preferred to be selected as master port.

Correct answer: B

Explanation

The correct answer is B because the spanning tree auto-edge setting allows the interface to remain in a forwarding state even during topology changes, ensuring continuous traffic flow. Option A is incorrect because the auto-edge setting does not disable spanning tree; it alters its behavior. Options C and D are also incorrect as they do not accurately describe the functionality associated with the auto-edge configuration.
